The Nikon Coolpix S800c is a compact point-and-shoot camera with smartphone-like Wi-Fi functionality. You can snap a photo and instantly upload it to Facebook or email it to friends, as long as you're connected to a Wi-Fi network.

Canon's PowerShot N digital camera features a fresh new design, with a tilting screen, no traditional shutter button, and built-in Wi-Fi® for easy photo sharing. The wide-angle lens zooms optically to 8X, giving you a wide range of shooting options.

No need to coddle the Olympus TG-830 iHS. Bring it into whatever extreme conditions you brave and document your adventures. Whether it's body-surfing in the ocean, or trudging through knee-high snow in sub-freezing temperatures, the TG-830 will not only survive but thrive, taking gorgeous photos and video.

The TG-850 is loaded with features that came in handy during my trip to New Mexico. The camera is compact, rugged and takes beautiful photographs. Built-in art filters let you access your creative side.
